It covers a measurement range of 0.1 to 12.1 inches with a stated accuracy of 0.0002 inches and a graduation of 0.001 inches. This level of precision makes it suitable for quality-control environments, tool rooms, and production lines where dimensional verification is critical. The unit ships with a case for protection and proper storage. Calibration masters of this type are handled by metrology technicians, quality engineers, and precision machinists.\u003c\/p\u003e\u003cp\u003eThe 93005 is applied in environments that demand traceable, repeatable dimensional reference standards. Typical use cases include setting transfer gauges, verifying bore gauge masters, and providing a known reference during inspection of machined components. It is appropriate for both job-shop and production-floor inspection stations where inside-diameter measurements must be confirmed against a reliable standard across a broad range spanning 0.1 to 12.1 inches.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMeasurement range of 0.1 to 12.1 inches covers a wide variety of bore and inside-diameter applications\u003c\/li\u003e\n\u003cli\u003eAccuracy of 0.0002 inches supports high-precision metrology and quality-assurance workflows\u003c\/li\u003e\n\u003cli\u003eGraduation of 0.001 inches provides fine resolution for setting and verification tasks\u003c\/li\u003e\n\u003cli\u003eIncludes a protective case for safe storage and transport of the standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a reference-grade calibration master for use with inside measuring instruments, bore gauges, and similar precision metrology equipment requiring a traceable dimensional standard in the 0.1 to 12.1 inch range.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eCalibration masters are handled by qualified metrology or quality-control personnel and do not require mechanical installation. Store the master in its included case when not in use to prevent damage to reference surfaces. Allow the master and any instruments being set to temperature-stabilize in the measurement environment before use, as thermal variation can affect readings at this level of accuracy. Follow applicable calibration procedures and documentation requirements for your quality management system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Measurement\u003c\/strong\u003e: 0.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Measurement\u003c\/strong\u003e: 12.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy\u003c\/strong\u003e: 0.0002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGraduation\u003c\/strong\u003e: 0.001 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Case\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 35 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 93005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51538277105970,"sku":"93005","price":10382.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f194c21958b32ef6eb85b4b1fc20feb5.jpg?v=1785821499","url":"https:\/\/voomisupply.com\/products\/starrett-93005-calibration-master-0-1-to-12-1-in","provider":"Voomi Supply","version":"1.0","type":"link"}
